The journals 62 are supported by bearings 64 on the bottom 65 of the trough 11. Spindles 66 are vertically supported by the journals 62 and are free to revolve in bearings 68, of cylinders 67, which are suspended from the tray 44, around its apertures 69. The spindles are provided with orices 79 and above the orifices are vertically mounted brushes 80.

On the hub 42 of the sleeve 41, is mounted a turn-table 70, provided with apertures 71. The apertures 71 surround hollow cylinders 72 which are provided with flanges 73 above the table 70. Over the flanges 73 and around the apertures 71 are mounted the flanges 74, of hollow cylinders 7 5, arovided with shoulders 76. Wedge cylinders 77, provided with shoulders 7 5', are mounted under the shoulders 76 of the cylinders 7 5.v Spring coils 78, are wound around the cylinders 77 under their shoulders and over the flanges 73 of the cylinders 72.

The cylinders 75 are uniformly distributed over the table 70, which is divided into sections 7 0 of a regular polygon whose center coincides with that of the table 70. Each section is provided with fourteen cylinders 7 5, uniformly distributed along radial lines. The spindles 66, which pass through the cylinders 67, of the tray 44, are confined within a space equal to one section of the table 70 and are distributed along radial lines and concentric with the cylinders 7 5.

A rinser trough 82 is supported by a bracket 81 at an angle with and above the trough 11. The trough 82 has its bottom 82 provided with a tap 83 for a water supply pipe 84. In the trough 82 is mounted an inverted pan 85 to form a reservoir 128 above the bottom 82. The reservoir 128 is provided with taps 86 for rinser-tubes 87 which are uniformly distributed over a section adjacent to that of the spindles and concentric with the cylinders 75, of a section 70 of the table 70. On the table 70 are mounted posts 92 which support a frame 90, provided with apertures 91 concentric with the cylinders 75, for vertically supporting the bodies of inverted bottles 88, whose necks 89 are inserted in t-he cylinders 75.

The split collar 47, carries a pin 161, pivotally supporting the arms 260 of a clamping device 93. From the clamping device 93 are suspended disks 94, for engaging t-he bottoms of a group of bottles of a section of the table centrally above a group of brushes 80. On' the clamping device I93 is mounted a weight 95. On the bracket 51, of the collar 50, is pivoted a lever 96, having an ar-m 97 pivotally connected with the clamping device 93, by a bar 98, and an arm 99 provided with a recess 100. On the 'bracket 55, of the collar 54,'is pivotally suspended a pin 101 provided with a cap 102, for engaging the recess 100. On the tray 44 is mounted a bracket 103 which carries a drip-pan 104 rearwardly vof the spindles and of the rinsers. The pan 104 is provided with a bottom 106 and is ind clined to drain the water from the bottles after they have been washed and rinsed into the trough 82. The trough 82 is provided with a drain 108 for draining into the trough 11, which is provided with a drain 109 for draining into the chest 7 provided with a drain-pipe 110. A lever 112, having a fulcrum 114, is provided with arms 111, pivoted on the collar 43, and with arms 113, carrying a rod 115. On the chest 7 is mounted a bracket 116, carrying a rod 117 on which are pivoted levers 118 and 118. The levers are provided with arms 119 and 119, carrying Weights 120, and with arms 121 and 121 pivoted on the rod 115. On the arm 121, of the lever 118, ismounted a bracket 122 slidingly supporting a rod 123, pivoted on a handle 124, operating a valveI 125, of a water-main 120 supplying water through the pipes 6 and 84, to the reservoirs 2 and 128.

On the socket 30, of the base 1, is mounted a bracket 129, provided with a slot 130 slidingly supporting a vertical guide 131` provided with stops 132 and 132. A slotted bar 134 is iixedly connected with the guiding bar 131 by a bar 133. The slotted bar 134 is provided with a collar 135` carrying a pin 136 adjustably mounted therein by locknuts 137. On the pin 13G is adjustably mounted the leg 139, of a T 140, by a locknut 138. The T 140 carries a horizontal rod 141 pivoted on the ulcrum 114, ot' the lever 112.

On the shaft 16, in rear oit the post 32, is mounted a crank 36, provided with a slotted arm 142 along which is clamped a pin 143 by a nut 144. On the pin 143 is mounted a roller 145 to roll inside the slotted bar 134 which consists o't` a horizontal section s, joined to a section u equal and opposite to said section s by a section t ot a radius equal to that of the roller, of a sec t-ion e having a radius equal to the distance of the center of the roller trom the axis of the crank plus the radius of the roller joined with the section s and with a section s equal and opposite to the section s, said section s joined with a section u equal and opposite to the section s by a section t equal and opposite to the sect-ion t, said sections u and u joined by a section fu which is equal and opposite to the section fu.

The driving gear 35 has a section 147 ot its periphery subtending an angle equal to that subtended by a section ot' the table 70 provided With bevel teeth, and a smooth seetion 148 of a diameter approximately equal to that of its pitch cone. The toothed section 147 is provided with end teeth 147 Which are joined with the smooth section 148 by inclinations 149.

The follower 40 is divided into sections. each subtending an angle equal to that subwith teeth 150 ol the same pitch and outline as the teeth oit' its driver 35, said sections joined together by lock teeth which extend to the pitch cone ot' the gears and whose outer faces 157 are joined by concave surfaces '1,51 for the convex surface 148 of the driver 35 to roll over. The object o1 the inclinations 149 is to permit the convex surface 148 to pass the middle of a lock-tooth and to release it just. before an end tooth engages the side of a lock-tooth and conunences to revolve the follower, said end teeth being heavy the better to withstand the shock caused at the moment of engagement'.

The crank 30 is keyed on the. shat't 11 in such a position that the rst line ot contact between a heavy tooth o1 the driver 35 and the first tooth ot' a section o'l.E the follower 40 and the line ot' contact between the roller 145 and the beginning of the section 'n ot the slotted bar lie approximately in a plane through the axis of the shaft 1G.

The relative positions of the other elements of the machine are as follows The tray 44, of the sleeve 43, is above the brushes which are confined within the cylinders suspended from the tray. rIhe cylinders 77 ot one section ot the table 70 are centrally above the brushes while the next succeeding section in the direction ot motion, as indicated by the arrow shown in Fig. 3, is centrally above the rinsers 87. .lhe clamping device 93 is centrally above the tray at a distance which is sutlicient to permit thc bottoms of the bottles carried by the table to pass by the disks suspended from said clamping device. The arm 99 ofi the lever 9G is depressed by the pin 101 which causes the bar 98 to hold the clamping device in the oblique position shown in Fig. 1. The remaining sections ol the table are directly above the drip-pan 104. The slotted bar 134 is at its highest position and the valve 125 is closed to eut ott' the water from the reservoirs.

Assume that the machine is now started by shifting the belt 20, b v means ot' the belt shifter 22, from the loose to the tight. pulley. The tight pulley 19 rotates the shaft 17, and its motion is transmitted by its gears 27 and 24 to the gears 28 and 25 respectively. 'l`he shaft 10V rotates with the gear 25 aml the gear 2G mounted thereon drives the doublet'aced gear a. of the train 63. The gear a drives the gears I), b, g and (Z: the gear b drives the gear c, the gear 7) drives the gear c', and the gear I drives the gear c. The gear g drives the gears d', 7) and a; the gear e drives the gear f', the gear drives the gear c. and the gear o drives the gear d. The spindles 60 are rotated by the train (i3 as long as the machine is in opera-tion.

The gear 28 is mounted on a bearing 152,

tended by a section ot' the table and provided ot' a collar 153 bolted on the transmitter shaft 14. rlhe collar is provided with a bracket 154 carrying a ring 156 which is surrounded by the rim 155 of the gear 28. The ring 156 is provided With a split 158. The split ring 156 carries a socket to one side of the split and. a bracket on the opposite side thereof. The bracket 159 is bored and threaded for a bolt 160 screwed through the bore and extending inside the socket 157 to press against a spring-coil 161 mounted therein. The bolt may be adjusted to produce a sufficient tension on the spring for causing the split ring to clutch the gear 23 to be revolved thereby When the shaft 14 carries a normal load. The moment the load becomes abnormal, the gear 28 commences to slip on the split ring, With the result that the split ring remains stationary.

When the load is normal, the gear 28 which meshes with the gear 27, of the power shaft 17, transmits the motion of said. shaft to the shaft 14 through the split ring 156. The gear 4, of the shaft 14, meshes with the gear 29 of the shaft 16 which is thereby caused to rotate continuously with the power shaft 17 as long as the load is normal. The gear 35 and the crank 36, mounted on the shaft 16, revolve continuously with said shaft. The gear 40 which meshes with the gear 35, is rotated intermittently during the engagement of its teeth with the teeth of the gear 35 and transmits said intermittent motion to the sleeve 39 mounted on the post 32 around which it is free to revolve between the rings 53 and 220. The sleeve 39 is provided With a key-Way 162, for a key 163 of the sleeve 41 which is slidingly mounted on said sleeve 39. The sleeve 41 is thus constrained to revolve with the sleeve 39 but is also free to slide thereon. The table 70, mounted on the hub 42- of the sleeve 41, is periodically revolved by the sleeve 39 and during such a period of motion one of its sections is transposed from a position over the tray 44, to a position above the rinsers, transposing the neXt succeeding section from its posit-ion over the rinsers to a position over the drip--pan, and a section from a position over the drip-pan to a position over the tray. During the aforesaid movement, the roller 145 carried by the arm 142 of the crank 36 rolls over t-he section o of the slotted bar 134, which section subtends an angle equal to that subtended by t-he toothed section of the gear 35, and the bar therefore remains stationary. At the moment the teeth of the gears 35 and 40 become disengaged, the roller 145 enters the section s and rolls over said section and over the sections t and u. During the aforesaid movement, the slotted bar descends, While the smooth section of the gear 35 rolls over a lock-tooth of the gear 40, said gear 40 remaining stationary. The roller then en ters the section fu and during its movement along this section the slotted bar remains stationary, While the smooth section of the gear 35 continues to roll over t-he aforesaid lock-tooth. The roller thenenters the section u', and as it rolls over said sect-ion and over the sections z5 and s the slotted bar ascends, While the smooth section of the gear Y35 continues to roll over the aforesaid locktooth of the gear 40 and the gear 40 remains stationary while the gear 35 completes a revolution. The movement of the slotted bar is transmitted through the lever 112 to the collar 43 and to the Weight carrying levers 118 and 118, one of which levers is operatively connected with the valve 125. Vhen, therefore, the slotted bar descends, the valve is opened and the Water from the main 126 is free to flow through the pipes 6 and 84 into the reservoirs 2 and 128, thence through the nozzles into the spindles and through the orifices around the brushes, and also through the rinsers. As the valve is opened, the collar carrying the tray 44 slides down, and the brushes are forced out of the tray cylinders and through the tray apertures. The sleeve 41 which is free to slide on the sleeve 39 folloivs the collar 43 and the brushes and rinsers are forced inside the bottles of the sect-ions of the table centrally above the spindles and rinsers. After t-he slotted bar has descended, it stops for a period which is coincident- With the movement of the smooth section of the gear 35 over a lock-tooth of the gear 40. The table, therefore, remains stationary While a group of bottles are Washed by the brushes, a group of bottles are rinsed by the rinsers, a group of rinsed bottles are being drained, While drained bott-les are removed and un- Washed bottles are mounted on the table. lVhen the slot-ted bar ascends, the valve is closed, and the water is cut off from the brushes and from the rinsers. The collar 43 ascends and is followed by the sleeve carrying the table. The brushes and rinsers are forced out of the bottles. The tray cylinders now surround the brushes and as the brushes revolve the dirty Water is pressed out and the dirt wiped away.

From the above it Will be observed that, While the gear 35 and the crank 36 are made to revolve continuously in parallel, vertical pla-nes, the gear 40 is made to revolve periodically in a horizontal plane, and the slotted bar 134 is made to move with a periodic reciprocatory motion in a vertical plane. During one complete revolution of the gear 35 and of the crank 36, the gear 40 rotates While the bar 134 is stationary, then stops While the bar descends, the bar then stops for a period equal to the period of motion of the gear 40 the said gear continuing stationary, the bar then ascends during a period equal to its periodl of Adescent t-he gear 40 having continued, stationary. There thus results a cycle of operations of a period equal to that of one revolution of the shaft 16 and comprising a period of motion of the gear 40 corresponding to a period of rest of the bar 134, of a descending movement of the bar corresponding with a period of rest ot' the gear and equal to two periods of its motion, followed by a period of rest of the bar corresponding with a period ot' rest of the gear and equal to its period of motion, and of an ascending movement of the bar corresponding with a further period of rest of the gear and equal to the period of the descending movement of the bar.

The sleeve 41 which is provided with a key 163 slidingly mounted in the key-way 162 of the sleeve 39 is revolved periodically by the gear 40 and during the motion of the gear 40 the table 70, carried by the hub 42 o'lf the sleeve 41, is revolved until a section is carried from a position above the brushes to a position above the rinsers and is then stopped. The collar 43 commences to descend with the tray 44, which causes the cylinders 67 to slide down the spindles 66. As the collar 43 descends, the sleeve 41 slidingly supported above said collar descends with the table and the cylinders 72 and 75 of the section of the table above the brushes are forced down the spindles which are forced through the apertures 69 o1' the tray 44 above the cylinders 67. The collar 45 lollows the sleeve 41 together with the collar 47 clamped around said collar 45 and with the collar 50 rigidly connected with the collar 47. As the collar 50 descends, the lever 96 is released by the pin 101 and the weight 95 causes the clamping device 93 to assume a position parallel with the table. The disks 94, suspended from the clamping device, are now in a position to press against the bottoms of the bottles whose necks are inside the cylinders 75 and whose bodies are supported in the apertures 91 of the frame 90. The brushes 80 are thus forced inside the bottles carried by the section of the table above the spindles and the rinsers project inside the bottles carried by the section of the table which is now centrally above said rinsers. As the collar 43 descends, the valve opens and water is forced through the spindles and rinsers into the bottles for washing and rinsing. The collar 43 is then caused to ascend while the valve is closing. The upward movement of the collar 43 is transmitted to the sleeve 41 and is further communicated to the collar 50 until the recess 100 of the lever pivoted on the collar 50 engages the cap 102 of the pin 101 pivoted on the bracket 55 of the collar 54. lhen the recess 100 becomes thus engaged, the lever 96 is operated to cause the clamping device 93 to lift the disks 94 oil' the bottoms o1 the bottles of the section of the table above the spindles. The table is new free to revolve,

and as this occurs at the moment when the teeth of the gears 35 and 40 become engaged and when the roller 145 enters the section v o1' the slotted bar, the sleeve 41 is prevented from sliding but is forced to revolve With the sleeve 39 and the table is caused to revolve. The lever 1112, which is now stationary, prevents the collar 43 from revolving, and the key 109 oil? the collar 50 in the keyway 170 of the post 32 prevents said collar 50 from revolving. The collar 45 is held by the collar 47 which is rigidly connected with the collar 50. The vertical displacement oit the sleeve 39 is prevented by the ring 53 l'astened on to the post 32 by the machine screw 171. The table revolves so long as the teeth of the gears 35 and 40 are engaged, and stops after it has revolved through an angle equal to that subtended by the toothed section of the gear It will be observed that, for the proper operation ot the machine, it is essential that the table should come to a stop at'ter its period of rotation in such a position that the brushes and rinsers would enter the bottles. This is accomplished in the following manner :"Each section of the table is provided with a lug 173 having a beveled face 183. On the posts 58 are mounted brackets 174 and 174 revolubly slmporting a horizontal rod 175. On the rod 175, between the posts and near the bracket 174, is mounted a lug 178, provided with a face 184 and carrying a pin 179. On the end 180 of the rod 17 5 is mounted a weight 181, and between said weight and the bracket 174 is wound a spring 182. On the rod 175. between the lug 184 and the bracket 174, is mounted a lug 200, which is always directly above a table lug when the table is moved either up or down. Vhen the table is made to ascend a table lug presses against the lug 200 which causes the rod, 175 to turn until it is counter-acted by the weight 181. As this occurs at the moment when the roller 145 enters the section o of the slotted bar, the downward pressure of the weight 181. is sufficient to cause the lug 200 to stop the table, which coincides with the posit-ion in which the table is :tree to pass by the brushes and rinsers. The table is now in its plane of revolution, and as it commences to revolve, the table lug is moved from under the lug 200. The Weight 181 is new free to cause the rod 175 to turn, until it is stopped by the in 179 coming in contact with the bracket 174. The lug 200 is now parallel lwith the table and directly in its plane oil. revolution. As the table continues to revolve in the direction of the arrow shown in Fig. 3, the lug 200 is met by a table lug with the result that the rod 175 is forced to slide and the spring 182 becomes compressed between the weight 181 and the bracket 174. The tension thus developed in the spring is sufficient to cause with a bracket 185, carrying a roller 186 Vwhat I now claim as new and desire to prothe lug 200 to prevent the table from being l revolved by its momentum after the teeth of the gears 35 and 40 are out of engagement. This causes the table to stop when the group of bottles to be washed are centrally above the brushes and a group of washed bottles are centrally above the rinsers. W'hen the table is made to descend, the lug held by the lug 200 descends with the table and the lug 200 is released. The spring is now free to expand which brings the lug 200 to its position centrally above the table lug.

To prevent the lateral displacement of the tray 44, when its collar 48 is made to slide up and down, or when the table is revolved with its hub 42 over the ball-bearings of the collar 48, I provide a guide 187, vertically supported by a bracket 188, mounted in the trough 11. The tray 44 is provided to roll along the inner surface of the guide 187. The bracket 188 is also provided with a bearing 189 for the power shaft 17 and with a recess 190 for the rod 191 of the belt shifter 22.

Vhen the table descends, the weight 95 forces the clamping device 93 to assume a horizontal position, and a group of bottles become clamped between the disks 94 and the cylinders 77 actuated by the springs 7 8. rPhe bott-les are thus held firmly and are prevented from becoming displaced by the revolving brushes. r1`he position of the disks 94 relative to the bottoms of the bottles is adjusted by loosening` the clamp 159, when the collar 45 can be turned by means of the handles 192 to cause the collar 45 to either ascend or descend until the clamping device 93 is in the proper position.

It will be observed that the machine illustrated in the drawings is built for handling siX groups of fourteen bottles each, and the only manual labor required is to remove drained bottles and mount unwashed bot tles. The same kind of a machine can be built for handling either a larger or a smaller number of groups of bottles, with more or less bottles per group.

lVith the arrangement as above described, drained bottles can be constantly removed and unwashed bottles mounted on the table, and as the bottles are handled directly and without the intervention of crates, which might sometimes interfere with the free movement of the machine, it may be operated at a very high speed.
